Application December 7, 1'942,,SerialNor 168,086 4 Claims 10145 5137)This invention relates to sets \ofnested leg sup- {ports for raising aselecteddistance theheight or articles of furniture, foreexampleldesks,chairs or tables. I

As is well known the height of conventional" pieces of furniture isfixedat the time of their manufacture and thereafter cannot beordinarily changed except by reconstructing the lees or other partsthereof." i i My invention therefore contemplates the 1 proyision ofasup'port whichis'arrangedto receive ,and thereby,.in efiect, increasethe length of aleg of thepi'ece of\furniturewhoselheightlitiis desiredto raise. i i

My invention still provision of a plurality of such supports, which @maybe nested togetherinsets, one stacked upon the other, :a set for eachleg of the article of furniture; to selectively raise the height of thepiece of furniture to-which they are applied.

My invention still further contemplates the provision of, such atset ofnested supports, in

which the units thereof otherthan the base constituting member oi a setare interchangeable.

My inventionstill further contemplates the provisional? suchzsuppori'swhich are substantial .inconstruction, constructed and arranged $05566.-

ceive furnitureflegs of a variety of sizes and shapes, neat inappearancesc, that they :blend withthe appearance ofthe piece offurniture to which they are applied and therefore do not mar it andwhich are relatively inexpensive to manufacture. i l

Other and further objects and advantages of the present invention willbecome apparent from the following description and the drawing inconnection therewith, in which Fig. 1 is a vertical sectional view ofthe base member of a set of supports, according to my invention andshowing in dotted lines the leg of an article of furniture arrangedtherein.

Fig. 2 is a plan view thereof.

Fig. 3 is a vertical sectional view of a set of nested supports,according to my invention, and showing in dotted lines the leg of anarticl of furniture arrangedin the top unit of th set.

Fig. 4 is a plan view of an interchangeable extension unit of a set ofsupports, according to my invention.

Fig. 5 is a perspective view of an article of furniture, such as atable, the legs of which are arranged in the base member of a set ofsupports to raise the height of the table. I

Referring now to the drawing, each set of supports comprises a basemember ID and one or any further contemplates the greater numberofuinterchangeable uppergor extension units: l2, which may be nested ineach other and in a base member i=0.

To :give greater stability to the ,SupDQrt and the articleof furniture.the height from the :floor of which is to be raised, and (to enhancethel 'ai pearance of the supports, I prefer to arrange on the basemember I0. a collar-like fiange l4 toiorm the cup or socket 1,6, in eachof: which sockets a :turniture leg i 8 is received. integral with andextending up, from the platform 20, the areaof *whichis ofdesiredmagnitude larger than. area of the preferably cylindrical leg receivingcup orv socket forming housing or flang M. It will ,be

understood that the platform 20 may bedispensed ,wvith. the base memberbeing cylindrical throughwout'orof any "otherselected shape and size,consonant with the desired stability of support,

In order toprovide a cup cr-socket I6, which will accommodate furniturelegs of divers sizes and shapesbIform the cupeor socket so that ithas a,relativelylarge diameter at the entrance thereto, which decreasesprogressively and uniformly downward to theufloor 2210f Lthecup orsocket.

I prefer to make smooth and unimpeded the inisidesurface 2d of thesocket which is preferably inthe shape of an inverted truncated cone,al-

though anyothe-r shape may be used.

Because of the decreasing inner socket diameter, legs ofdiiierent sizesmaybe used with the supports, the smaller the size or width of the leg,

which is received in the cup or housing, the closer to the floor 22 willit be positioned and the larger the size or width of the leg the closerwill it be positioned to the upper edge 26 of thecollar l4.

Because of the uniform decrease of the inside diameter, particularlybecaus of the unobst'ructed inside, surface 24 of the socket, afurniture leg arranged therein will be wedged in the socket by theweight of the article of furniture.

While I prefer to make my furniture supports from wood because of theeaseand relatively inexpensive wood turning operations used, and thecomparative softcharacteristic of such material, it will be understoodthat these supports can be made "from any other material, for exampleplastic or metal.

Referring now to Fig. 5 wherein I illustrate an example of the use of myinvention, should I it bedesired toraise the height of the top sur- 1face 28 of the desk or table 30, the legs l8 thereof are each arrangedin the socket or housing of the base member I 0 of a set of my supports,

in effect to thereby increase the length of the sion units I2, which areinterchangeable with each other and which may be nested together and inthe base member ID, as illustrated in Fig. 3 to increase, as desired,depending on the number of upper units used, the effective height of thesupport.

The outside surface 34 of each interchangeable extension unit I2 isformed of shape, corresponding in size and configuration to the shape ofthe cup or socket I6, of a base member so that it can be seated, nestedtherein (in the illustration that of an inverted truncated cone).

Similarly each extension unit is provided with a socket 36 having arelatively large diameter at the upper edge 38 thereof, or entrancethereto, which decreases progressively and uniformlydownward to thefloor 40 of the socket 36.

The sockets 36 of each upper or extension unit is the same in size andshape as that of any other upper or extension unit and of the basemember socket l6 so that furniture legs of divers shapes and sizes willbe accommodated in any one of them and so that the extension units maybe interchangeably nestedin the base member 7 to adjust the height ofthe support to any selected magnitude.

While I have illustrated in Fig. 3 my supports as comprising a setconsisting of a base member and two extension units, it will beunderstood that any greater number of upper or extension units may beincluded in each set of supports.

While I have described an embodiment of my invention, I do not intend tobe limited to the specific details thereof but intend that my inventionbe limited only by the scope of the appended claims and the state of theprior art.

I claim:

1. An extensible'device in the form'of a set of nested supports foradjusting the height of an article of furniture, comprising a basemember having a platform rectangular in form and a collar having adiameter less than the base and extending up from the platform, theinterior of said collar forming a socket to receive and house therein aleg of an article of furniture the height of which is to be raised, theinterior of said collar constituting acup in the shape of an invertedtruncated cone and an extension unit, the exterior of which correspondsin size and shape to the said cup for nesting the extension unit in thebase member, the interior of said extension unit corresponding in sizeand shape to the cup.

2. An extensible device for adjusting the height of an article offurniture, in the form of a set of nested supports comprising a basemember and an extension unit nested therein, said base member having acup-like interior for receiving therein a leg of the article offurniture the height of which is to be adjusted, said cuplike interiordecreasing in ection uniformly progressively from the top edge of themember to the floor thereof, the exterior of the extension unitcoresponding in size and shape to the cup-like interior of the basemember for nesting the extension unit therein and said extension unithaving a cup-like interior decreasing in section uniformly progressivelyfrom the top edge of the extension unit to the floor thereof.

3. An extensible device for adjusting the height of an article offurniture, in the form of a set of nested supports comprising a basememthereof.

,4. An extensible device for adjusting the height of an articleoffurniture, in the form of a set of nested supports for each leg of thearticle of furniture, each set comprising a base member and an extensionunit removably nested therein, the interiors of both the base member andthe extension unit decreasing in section from the edge to the floorthereof.
